Be it, known that I, ARTHUR KrrsoN, a subjeet of the Queen of Great Britain, and a 'resi'- dent of Philadelphie, (Germantown) con may of Philadelphia., State of Pennsylvania, have in venized certain new and useful Improvements ,in Vaporizing-Tubes, of which the fo1 lowing is e speoieation'. n

My inveneion'relates te automatic ont-0136s for vapor-burning apparatus; and more speeieeliy it consists of a. thermostetie valve so constructed end loeabed as to operaieemo-` maticaily and shut off the How o! oil to the he pparabne wheny vaporizing-ehember of the liame goes out.'

Thel ebje'et `of my invention is to ya. uteimitieelly prevent this, and it accomplishes it by means of a. thermosietie valve, which is normally closed ai atmospheric; temperature, thereby hunting v0H all iiow of oil, and only opens te admitoil to the veporizi:xg-chamber: when the mempereiureof the seme has been miied'w Fig. 3 ish similar erossfeecigipn .on line .e9-sof Fig.' 1.

The mede oopemtion of-my invention is 'ne follows: The veporizinfgmuhe being ieeei'bed in the-lempex' oiherfiegiohnmingeppareisns, the ennneetion o he vaiveplunger @with or'o n. Bonson bnrneri broughtabout in any one of the well-known ways forthe purpose of storting' the lamp into operation, the rod 9 will expend fester than the vo'porizing-tuhe -1 and the plunger G of the lneedle-volvo will be lifted non? icient distance from its seat topermit oil to pass throng-h to the vaporizing tube cr c'hninber. in the requisite quantityn The controllingwnive 4 is then openedmnd the oil under pressure posses into the vapori sin g tube or chamber 1- and is there turned into vnpor, issuing from the orifice 11 in' the form ofc. jet. The vapor thus formed is burned in the vaporhu rner in the wellfxnown way,-aud the heat of thebnrner maintains the tube l at 'the necesisory temperature for continued vaporizstion of the oil. So iong es this temperature is maintsined the thermostat-valve is open. If, however, the lamp goes out for any reason whetover, the' vnporizingtube and its contained thermostst cool down andthethermostst acts to automatically-'close the needlevalve and prevent further flow of oil. of? the thermostat stretches the ports so that the needle-valve opens to eh unnecessary extent when the lamp ie in operation or does not close tightly when it ie out of operation, the trouble con be remedied by removing the screwpiug i end using a small screwdriver to rotnte the plunger, thereby ,takingnp the ediustnble screwohreaded connection of said plc ngerwitli the thermostat to a degree which will. put the ports in proper relation for re newed snccessful operation.

To prevent promotore opening of the vclvel 1* the resulting o'odng of' the vsporiziug chercher, connections, dtcwvthe valve should be adjusted to remain closed until the vapo` rinintube hss been raised tothe temperature necosscryto repcrizc the oii, and es this point oi. 41volrre-ciocoing" can ,only be determined by ect-usi tcststbe vsive and thermostat sections nre, therefore cdjnstably connected in .the ansnner described to enable the valve to be residiiy adjusted and properly set to open at n, 'predetermined temperature.

The arrivent-:igen of my invention nre of course in the saving of the Waste of oil and in. the prevention of deinngeby such waste oii end also in removing all danger of fire which might result from tryingto start up the lenen when it was full of oil -nndV surrounding objects were saturated with the same. More over,.whle my invention accomplishes the above objects automaticallyand effectively it odds but little to the cost of the lmnp and is entirely hidden nud self-contained within the ordine-r3;-Y izirnp concretos. lt is also reediiy edjuemhlo rind does not in any way inter-- When, however, the' preheating- Ii? the contraction thermoststicslly closed 'under heet is greater than that of fera with the ordinary manipulation of the lamp parts.

It is evident of course that various-changes' could be made in the details of construction illustrated without departing from the spirit and scope of lmy in venton so long as the principle of operation described in the specificotion or the general relative arrangement of ports illustrated iu the drawings is preserved. Otherforrns of thermostat might be em ployed, and different forinsof valve might be substituted. The thermostirt might be differently located so long ns it is within the heating zone of the lamp-burner and of the preheeting device. The feature of hllcwing out the ther mostnt-rod might he dispensed with, though l' prefer the hollow form, ns it economizee ma# teriel without secricing stiffness of the rod and also renders the. thermostat more susceptible to variations in ternfJerature, as of course the amount of heat necessary to raise the thermostat to' s given temperature decreases ns the amount of material to be heated decreases.

Having therefore what I claim as new, 'and desire to protect hy Letters Potent, is
